The issue in this case is first whether you actually knew that the driver was restricted. You can only be charged with aiding someone to commit an offence, if you had the necessary knowledge. However now that I have seen the ticket, I suspect that the police are attempting to use the provisions of the Crimes Act which referred to aiding and abetting someone to commit an offence. It is of course an offence under the Land Transport Driver Licensing Rules*****contrary to the conditions of a restricted license, and this carries 35 demerit points, plus the fine. Section 66 of the Crimes Act does say that anyone is a party to an offence who abets any person to commit the offence or incites someone to commit the offence. So if you did not know that the driver was restricted, then you should defend this case.
